QTextBrowser and 'sticky' link on 3rd edition devices

**Jon Heron** · 2011-02-13, 18:04

Hello All,

Let me preface by stating I am likely doing something wrong here...

I have an about screen that utilizes a QTextBrowser for the 'about' text as well as the support email and website links.
My code works fine on all touch devices and the desktop, however, on 3rd edition devices the cursor gets 'stuck' on the email link. In other words when the user scrolls down the About page, as soon as the cursor hits the email link the cursor freezes on the link and cannot be moved, thus the user must close the about dialog to continue.
If I enable the textEditable property I can then scroll past the email link but the about screen then always opens with the cursor at the bottom of the screen instead of the top, I use ui->textBrowser->moveCursor(QTextCursor::Start); to set the cursor to the top of the page.
Here is my code, bear in mind that I am a beginner to C++

Code:

aboutDialog::aboutDialog(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::aboutDialog)
{
    ui->setupUi(this);
      //set cursor to top of text window
     ui->textBrowser->moveCursor(QTextCursor::Start);
     //connect link clicked to open
    connect(ui->textBrowser, SIGNAL(anchorClicked(QUrl)),this, SLOT(openUrl(QUrl)));
    //set back soft key
    back = new QAction(tr("OK"), this);
    back->setSoftKeyRole(QAction::PositiveSoftKey);
    connect(back, SIGNAL(triggered()), this, SLOT(backButton()));
    //set exit softkey
    aboutDialog::addAction(back);
    ui->textBrowser->setFocus();
    }
void aboutDialog::openUrl(QUrl link)
{
    QDesktopServices::openUrl(QUrl(link));
}

Here is the HTML source from the textBrowser;

And finally here is the textBrowser property's from the ui_aboutDialog.h header;

Code:

        textBrowser = new QTextBrowser(scrollAreaWidgetContents);
        textBrowser->setObjectName(QString::fromUtf8("textBrowser"));
        QSizePolicy sizePolicy(QSizePolicy::Preferred, QSizePolicy::Preferred);
        sizePolicy.setHorizontalStretch(0);
        sizePolicy.setVerticalStretch(0);
        sizePolicy.setHeightForWidth(textBrowser->sizePolicy().hasHeightForWidth());
        textBrowser->setSizePolicy(sizePolicy);
        textBrowser->setMouseTracking(true);
        textBrowser->setContextMenuPolicy(Qt::NoContextMenu);
        textBrowser->setAcceptDrops(false);
        textBrowser->setFrameShape(QFrame::NoFrame);
        textBrowser->setFrameShadow(QFrame::Plain);
        textBrowser->setTabChangesFocus(true);
        textBrowser->setAcceptRichText(false);
        textBrowser->setTextInteractionFlags(Qt::LinksAccessibleByKeyboard|Qt::LinksAccessibleByMouse|Qt::TextBrowserInteraction|Qt::TextSelectableByKeyboard|Qt::TextSelectableByMouse);
        textBrowser->setOpenExternalLinks(true);
        textBrowser->setOpenLinks(false);

Can anybody see where I am going wrong with this?
I have a suspicion that it is a bug with Qt creator 2.01 but I dont have enough coding experience to be sure!
Thanks for any and all assistance!

Here is a complete test application that reproduces the problem, including in the S60_3rd_FP1_4 SDK emulator via creator.
